We performed a comparison between Dell XtremIO and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"One of the best features is the support, which is excellent."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"The most valuable features of this solution are its ease of use and performance."
"It has good, reliable, fast storage."
"The solution is very straightforward to set up."
"We mostly use it for backup, because we cannot measure anything, and we are afraid to use it for surveillance systems. We were planning to use it for mostly for surveillance systems."
"Initially, we faced numerous issues with our analytical systems. However, we saw performance improvement after the implementation of the solution."
"The program is very stable."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"Dell XtremIO is good for databases and huge workloads."
"Thin storage allocation"
"Deduplication and cloning capability"
"The most valuable feature of Dell EMC XtremIO is the data protection (DP) group, it is one of the most advanced features in these types of arrays. The dedupe and compression that this array provides both do a superb job."
"It allows us to put our infrastructure in remote locations and still get the same performance we get from our onsite SAN solutions."
"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."
"The newer versions of this solution are much more stable and easier to manage."
"The solution's technical support is good."
"The scalability has been quite good."
"The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
"VMware vSAN is compatible with the legacy hypervisor solutions and most of the features are good."
"The high availability is very good."
"The tool's pricing is higher than competitors."
"I want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"The tool's portfolio is minimal. It is expensive."
"Many options to check performance, like read, writes, random writes, and random reads, are missing in Pure FlashArray X NVMe."
"It is on the expensive side."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"They could add more support for file storage and different types of storage."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"They can improve the product by providing an HTML5-based interface instead of the Java GUI based application."
"I am not too impressed with XtremeIO because we had a major failure."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"XtremIO needs to be lower priced. It also needs better endpoints and scalability."
"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."
"Get rid of the Java aspect of the GUI console."
"I would like to see the ease of deployment and built-in Metro clustering."
"The GUI could be modified more in terms of how the different components are linked to each other."
"There are certain shortcomings in the stability of the product where improvements are required."
"It is an expensive solution."
"The solution must provide better customization."
"I would like to be able to limit IOPS."
"We are facing some problems with updates with the VMware vSAN. When we upgraded from version 6.5 to 7, we have been faced with many problems. They have been deploying many hotfixes for this version, and they need to continue to improve this version."
"If one node out of your ten nodes fails, it takes a lot of time to replicate and rebalance VMware vSAN. This time can be reduced. When a node fails and the data is not accessible, vSAN has to be rebalanced to make the redundancy level of two again. However, if it is taking a lot of time and any other hardware fails during that time, then we have a problem. Two disk failures mean that all data will be lost, and we may have to recover it from the backup. So, the number of threads that run to do the rebalancing could be more so that the time taken to make it fully redundant again is not so much."
"While I like the replication and compression features, there is a problem with them running too slowly."
"I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment."
